P'ORATION OF NEW YORK.

YORK, A COB- IMILL-ROLL STAND.

Original application filed August 25, 1920, Serial No. 405,996. Divided and this application filed J1me 1, 1923. Serial No. 642,755.

To all whom it may concern:

Be it known that we, JAMns A. CAMERON and GIJSTAI B. Enron, citizens of the United States, and residents of the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have in vented certain new and useful Improvements in Mill-Roll Stands, of which the following is a specification.

This invention relates generally to mill or web roll stands such as are employed in connection with printing, slitting or other machines that act on a web of flexible material, and has for its main object and feature the provision of combined means whereby the web roll may not only be brought into registry with the rolls of the machine with which it is associated, but the web roll shaft may also be made parallel with the rolls of said machine.

This application is a division of application Ser. No. 405,996, filed August 25, 1926.

In the accompanying drawings the invention is disclosed in a preferred form in which:

Fig. l is a view in elevation, with parts broken away and in section, largely diagrammatic, of a slitting and rewinding machine showing a mill roll stand, embodying the invention, associated therewith.

Fig. 2 is a view looking in the direction of arrow 2 of Fig. 1, showing one end of the mill roll stand with some parts in section.

Fig. 3 is a vertical sectional view on the plane of line 33 of Fig. 2.

Fig. 4 is an end view of the controlling means for the brake looking in the direction of arrow 4 in Fig. 5.

Fig. 5 is a top plan View of the controlling means for the brake looking in the direction of arrow 5 of Fig. 1.

15 indicates a machine such as the well known Cameron slitting and rewinding machine for acting on a web of paper or other flexible material coming from a removable web roll 16. The slitting and rewinding machine has a plurality of rolls, as indicated, through which the web passes and the problem is to provide means whereby when a web or mill roll is placed in position in the stand it may be brought into registry with the rolls of the slitting machine and whereby the mill roll shaft may be brought into parallelism with the rolls of said slittin machine.

1 is a m.ll roll shaft supporting the web of paper removably, slidably and rotatably mounted in open swivel bearings, preferably constructed in accordance with the disclosure of the application previously recited, one of which is shown at 18 and having a flexible driving connection, such as universal coupling 20, with control shaft 21. 22 is a stationary bearing provided with guideways 23 for the reception of slide 24 carrying control shaft 21 and providedin its upper surface with rack 25 with which inion 26 engages. This pinion is mounte on actuating shaft 27 extending transversely of control shaft 21 and mounted at one end in bushings 2S and at its other end in a suitable bearing 29. 30 is a stop limiting the rotation of shaft 27 in either direction. It will he understood that by turning handle 31 on shaft 27, sliding member 24 and with it control shaft 21 will be moved longitudinally of the axis of said shaft, and, owing to universal joint 20, mill roll shaft 17 will lkewise be moved lengthwise and, that this may be effected whether or not mill roll shaft 17 is axially coincident with, or angularly displaced with reference to, the control shaft. 59 indicates a second bearing for shaft 21.

Mounted on shaft 21 and movable lengthwise therewith is a brake drum 34. Mounted at the lower end of slide 24 is a bushing 60 carrying a shaft 61 having a bell crank 62 one arm of which is connected to one end of brake band 39 and the other end of which is connected by rods 63 to the other end of said brake band. The up or arm of hell crank 62 is bifurcated an is connected to rod 64. Connected to bell crank 62 is an arm 65 carrying weight 66 that tends normally to swing to the right and to release brake band on drum. When rod 64 is pulled to the left in Fig. 1 the brake band is tightened thus retarding rotation of shafts 21 and 17. W hen shaft 27 is turned slide 24 will be moved carrying with it shafts 21 and 17 and bushing 60 carrying a rockshaft 61 so that the brake moves as a with the mill roll and control sh-if ts. V r 7 Any suitable means may be used to actuate rod 64, but in the present instance the fiillowing means are used. 67 is a bell crank mounted on stud 68in framework 69. One arm of this bell crank is connected to rod 64 and the other arm is bolted I and in full lines in Fig. 4, the pedal being giyen', if desired, slight sidewise movenent to Permit pawl 72 to engage rack 73 thus retaining the brake band taut condition. To release the parts, the operator kicks the pedal downwardly and sideways and Weig'ht 66 will then release brake band move "pedal and pawl'upwardly into the dotted line position indicated in Fig. 4.

i We claim:

1. A stationary bearing having guides, a sliding member, having a downwardly projjecting portion, sliding insaid uide' s', a con trol 'shaftcarried' by said slid ing member, a'biake' drum mounted on said control shaft,

a brake band surrounding said'driun, a

rocks'haft mountedin said downwardly projecting portion, a bell crank, carri'e'dhy said rockshaft, connected to opposite ends of the brake band.

2. A stationing bearing having guides, a sliding member; 'aving ifdowniivardiy projecting portion, sliding in said guides, a control shaft carried by said'sliding member, a brake drum mounted on said contnol shaft, a brake band surrounding said drum, a rockshaft mounted in said downwardly projecting portion, a bell crank, carried by said rockshaft, connected to opposite ends of the brake "band. a pedal connected to said rockshaft. a pawl on said pedal, and an upri ht stationary rack to engage with said paw? A stationary bearing having guides, a sliding member, having a downwardly projctin' portion, sliding in said uides, a control siaft carried by said sli ing member, a'brake drum mounted on said control shaft, a brake band surrounding said drum, a rockshaft mounted in said downwardly projecting portion, a bell crank, carried by said rockshaft, connected to opposite ends ofthe brake band, a pedal connected to said rockshaft, a pawl on said pedal, an upright stationary rack to engage with said pawl, and a weight connected to said rookshaft for normally releasing'the brake band;

Signed at Brooklyn, in the county of Kings and State of New York, this 23st day of May, 1923.
